    New Specification for Archiving Traffic Incident Characteristics and Management Data

    (What is a Work Item?)

    WK35917

    1. Scope

    This specification will provide two products: (1) data dictionary for archiving data related to traffic incidents and (2) standard data management and processing methods for turning the data into incident-related performance measures. The types of data to be covered include the characteristics of incidents including type, severity level, vehicles involved, duration of the incident (including decomposition of total duration into timeline information), and detail on lane blockages caused by the incidents. This standard will provide a consistent basis for developing performance measures, for establishing benchmarks, and for comparing performance across areas. Performance measures will relate to documenting the incident timeline, lane and shoulder blockages as they change throughout the course of a single incident, and secondary crashes. It also will provide system developers guidance in the construction of data management systems.

    A review of traffic incident data being archived by traffic management centers showed little consistency in data definitions, data structure, and processing methods. The lack of data and data consistency hinders the development of performance measures that can be used for transportation agencies to assess and improve their traffic incident management activities. Given the growing emphasis on performance-based management of transportation investments, it is critical that adequate data be made available and that performance measures are
